The first line contains an integer , the number of test cases.
Each of the next pairs of lines are as follows:
- The first line contains an integer , the number of people in the queue
- The second line has space-separated integers describing the final state of the queue.
2 t = 2
5 n = 5
2 1 5 3 4 q = [2, 1, 5, 3, 4]
5 n = 5
2 5 1 3 4 q = [2, 5, 1, 3, 4]
Test Case 1
The initial state:
After person moves one position ahead by bribing person :
Now person moves another position ahead by bribing person :
And person moves one position ahead by bribing person :
So the final state is after three bribing operations.
Test Case 2
No person can bribe more than two people, yet it appears person has done so. It is not possible to achieve the input state.
